For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of the present invention, "plurality" means two or more than two, unless otherwise clearly and specifically defined.

[0035] Please refer to Figure 1 and Figure 2 A material crusher comprises a casing 1, two crushing plates 2, two first adjusting mechanisms 3, two crushing rollers 4, a driving mechanism 5, a first guide plate 6, a second adjusting mechanism 7 and a second guide plate 8.

[0036] like Figure 1 As shown, the casing 1 has a cavity 1a and a feed port 1b and a discharge port 1c connected to the cavity 1a; in this embodiment, the feed port 1b is arranged at the top of the casing 1, and the discharge port 1c is arranged at the bottom of the casing 1, so that the material can smoothly enter the casing 1 through the feed port 1b and can be smoothly discharged from the casing 1 through the discharge port 1c.

[0037] As a matter of course, there is a certain gap between the casing 1 and the ground to facilitate the discharge of the crushed materials from the discharge port 1c.

[0038] like Figure 1 As shown, two crushing plates 2 are slidably disposed in the cavity 1a, and the first adjustment mechanism 3 is used to adjust the position of the crushing plates 2 in the cavity 1a; specifically, the first adjustment mechanism 3 includes a second motor 33, a first screw rod 32 and a slider 31.

[0039] The slider 31 is slidably arranged in the cavity 1a along the horizontal direction, and the facing sides of the two sliders 31 have an arc for installing an arc-shaped mounting plate; one end of the slider 31 has a threaded hole, and the first screw rod 32 is rotatably arranged in the cavity 1a, and the second motor 33 is arranged on the outer wall of the casing 1, and its output shaft passes through the casing 1 and is connected to one end of the first screw rod 32. The first screw rod 32 is driven to rotate by the second motor 33, so that the slider 31 drives the crushing plate 2 to move in the cavity 1a, thereby changing the position of the crushing plate 2.

[0040] like Figure 1 and Figure 2As shown, two crushing rollers 4 are rotatably arranged in the cavity 1a and are located between the two crushing plates 2; the driving mechanism 5 drives the two crushing rollers 4 to rotate in opposite directions or in opposite directions, so as to crush different types of materials; specifically, the driving mechanism 5 includes two gears 51, a first motor 52, two pulleys 53 and a belt 54.

[0041] One end of one of the crushing rollers 4 extends outside the casing 1 and is connected to one of the pulleys 53. The two gears 51 are meshed with each other and are respectively sleeved on the two crushing rollers 4. The other pulley 53 is connected to the output shaft of the first motor 52, and the belt 54 is sleeved on the two pulleys 53. The first motor 52 drives one of the pulleys 53 to rotate, and under the action of the belt 54, the other pulley 53 drives one crushing roller 4 to rotate. Since the two gears 51 are meshed, the rotation directions of the two crushing rollers 4 are opposite or opposite. By changing the rotation direction of the output shaft of the first motor 52, the two crushing rollers 4 can be rotated in the same or opposite directions.

[0042] It should be noted that the crushing roller 4 is provided with a plurality of blades along the circumferential direction, so as to have a crushing effect on the material.

[0043] It should also be noted that the facing surfaces of the two crushing plates 2 have a plurality of serrations respectively; when the two crushing rollers 4 rotate in opposite directions, the blades on the crushing rollers 4 and the serrations on the crushing plates 2 work together to crush the material; at the same time, the position of the crushing plate 2 is changed by the first adjusting mechanism 3, the gap between the crushing plate 2 and the crushing roller 4 is adjusted, and the particle size of the material after crushing is adjusted.

[0044] like Figure 1 As shown, the second guide plate 8 is arranged in the cavity 1a and is located between the discharge port 1c and the two crushing rollers 4; the second guide plate 8 has a triangular structure, and when the two crushing rollers 4 rotate in opposite directions, the crushed material hits the second guide plate 8 at high speed, is further crushed, and falls out of the discharge port 1c after rebounding; when the two crushing rollers 4 rotate in opposite directions, the crushed material is diverted through the second guide plate 8 and discharged from the discharge port 1c.

[0045] like Figure 1 As shown, the first guide plate 6 is of a triangular structure, is slidably arranged in the cavity 1a along the horizontal direction, and is located above the two crushing rollers 4; the second adjustment mechanism 7 drives the first guide plate 6 to slide in the cavity 1a; specifically, the second adjustment mechanism 7 includes a third motor 72 and a second screw rod 71, one end of the first guide plate 6 has a threaded hole, the second screw rod 71 is rotatably arranged in the cavity 1a, one end of the second screw rod 71 passes through the threaded hole, and the other end is connected to the output shaft of the third motor 72, and the second screw rod 71 is driven to rotate by the third motor 72, so that the first guide plate 6 slides horizontally in the cavity 1a.

[0046] When the two crushing rollers 4 rotate in opposite directions, the third motor 72 drives the second screw rod 71 to rotate, so that the first guide plate 6 is located directly below the feed port 1b. After the block material to be crushed passes through the feed port 1b, it is diverted by the first guide plate 6, so that the block material falls toward the gap between the crushing roller 4 and the crushing plate 2; when the two crushing rollers 4 rotate in opposite directions, the third motor 72 drives the second screw rod 71 to rotate, so that the first guide plate 6 is close to the inner wall of the casing 1, and the slender material to be crushed enters from the feed port 1b and is located between the two crushing rollers 4.

[0047] The working principle of this embodiment is:

[0048] When it is necessary to crush slender materials, the first guide plate 6 slides to one side, and the driving mechanism 5 drives the two crushing rollers 4 to rotate in opposite directions. The slender materials enter the cavity 1a from the feed port 1b, and the two crushing rollers 4 complete the crushing of the slender materials and discharge them from the discharge port 1c; when it is necessary to crush block materials, the first guide plate 6 slides to the middle of the two crushing rollers 4, and the driving mechanism 5 drives the two crushing rollers 4 to rotate in opposite directions. The block materials enter from the feed port 1b, are diverted after passing through the first guide plate 6, and are crushed with the cooperation of the crushing rollers 4 and the crushing plate 2; at the same time, the gap between the crushing plate 2 and the crushing roller 4 can be adjusted by the first adjusting mechanism 3 to adjust the size of the particle size after crushing.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
